Introduction and Objective: The ideal instrument for initial periodontal therapy should enable the removal of all extraneous substances from the root surfaces without any iatrogenic effects. Because of that the objective of this study is to analyses and to compare the root surface roughness after using Gracey curettes, and a piezosurgery driven root planning tip, using SEM scanning electron microscopy.
Aim: The aim of this study was to compare root surface characteristics following root planing with hand- instrument and piezo surgery driven root planning tip instruments.
Material and Methods: A2 mm, 2 mm interproximal root area of 20 teeth (n = 40 surfaces) was evaluated by scanning electron microscopy (·50 to ·1000 magnification). Teeth were randomly assigned to the following two groups: Gracey curettes with 20 vertical strokes; and a piezosurgery ultrasonic scaler in mode ROOT with a power of two. In each case the evaluation for root surface roughness before and after root planing and surface roughness using the Index ‘t’ test ‘p’ value was measured.
Result: SEM microscopy reviled, the mean preoperative surface roughness was 3.587 with a standard deviation of 0. 466. The samples were root planed by curettes (Gracey) and the mean post-operative surface roughness was 2.364 with a standard deviation of 0.345. The results show that there was average surface roughness reduction in group A, following root planing by curette instrument, with ‘t’ value of 6.670 and ‘p’ value of =0.0000129. The ‘p’ value was more than 0 .01.
Conclusions:Out of the two instruments, namely Gracey curette, and piezosurgery driven root planning tip, were effective in mechanical debridement of the root surface. The results favored the use of piezo surgery root planning tip to achieve a smooth, clean root surface; however, the use of piezo surgery instrument tip was more time consuming, which might limit its use in clinical practice. Further clinical studies are needed.
